A Juneau judge has ordered a hearing about whether the court should review confidential personnel and internal affairs files of police officers involved in the April 7 standoff with former police lieutenant Troy Wilson. Wilson is charged with attempted murder and assault for shooting at officers who responded to a 911 call at his home.

Wilson’s attorney, Julie Willoughby, requested the closed-door hearing in November, saying she can disclose a “good faith basis” for her belief that an in-camera review of those files would lead to relevant evidence in the case.

An in-camera review by the court allows a judge to privately review documents before deciding whether to release any relevant information to attorneys.

Willoughby had argued in her previous motion the files may lead to information concerning “the biases, prejudices or ulterior motives of the various Juneau police officers who conducted the investigation of this case and who are alleged victims in the case.”

Judge Philip Pallenberg scheduled the hearing to take place on March 29 and agreed with Willoughby that it should be closed to the public since it involves confidential records.

Wilson is still being held on $1 million bail, and he is currently slated to stand trial in April. His trial has been postponed twice already due to extensive pretrial motions, and a defense motion to dismiss his indictment is still pending.

He’s facing a total of 22 charges for attempted murder, assault, weapons misconduct and criminal mischief. Twelve police officers are named as victims in the indictment.

Wilson, 45, had resigned from the Juneau Police Department prior to his April arrest as he was being investigated for off-duty behavior that allegedly violated police policy and procedure, police said previously. At the time of the shooting, Wilson worked as a juvenile probation officer under the state of Alaska’s Division of Juvenile Justice.

Prosecutors say Wilson barricaded himself in his house and fired about 75 to 100 shots at responding police officers with high-powered rifles and handguns. He surrendered after about five hours, and no one was injured during the incident.
